摘要:
A sliding component has a multi-layer structure having a sliding portion configured to undergo sliding contact with a surface of another component different from the sliding component. A lubricating oil retaining/supplying structure retains a lubricating oil and supplies the lubricating oil to the sliding portion during sliding contact between the sliding portion and the surface of another component irrespective of a contact angle between the sliding portion and the surface of the another component.
摘要:
The present invention aims to provide a sliding component of high wear resistance having a lubricating oil retaining structure and a structure helping to supply a lubricating oil regardless of the contact angle between itself and the mating component.There is provided a precision machinery component having at least three layers stacked together, characterized in that a portion substantially parallel to the stacking direction has a sliding portion coming into contact with another component, and that at least a part of the sliding portion has a recess.

A detent escapement for a timepiece has an escape wheel and a balance that freely oscillates about a balance staff and includes an impulse jewel that contacts a wheel tooth of the escape wheel and an unlocking stone. A blade includes a locking stone that contacts the wheel tooth of the escape wheel and is supported so as to be capable of approaching to and separating from the escape wheel. A one-side actuating spring contacts the unlocking stone and is elastically deformed along the approaching and separating direction with respect to the blade. The blade is constituted of a blade main body and a blade adjustment portion that is separated from the blade main body.

A detent escapement for a timepiece capable of decreasing energy loss with respect to a free oscillation of a balance and improving a timekeeping accuracy is provided. In addition, a detent escapement of a timepiece capable of realizing miniaturization and suppressing variations in the accuracy of a finished product due to assembly errors is provided. A one-side actuating spring of a detent 7 is formed so that a maximum stress portion, which is generated at the time of operating due to the contact of an unlocking stone 4 when a balance 5 is return-rotated, is present to be perpendicular to a first straight line L1 which connects the center of the balance staff 9 and a fulcrum 23a of the blade 23, and to be the side opposite to the balance by a second straight line L2 which passes through the fulcrum 23a.

摘要:
A detent escapement for a mechanical timepiece includes an escape wheel, a balance mounted for undergoing oscillation movement about a balance staff, a blade and an actuating spring. The balance has an unlocking stone and has an impulse jewel for contacting a wheel tooth of the escape wheel. The blade has a locking stone for contacting the wheel tooth of the escape wheel and is supported for undergoing movement in approaching and separating directions relative to the escape wheel. The actuating spring is configured to contact the unlocking stone and is mounted for undergoing elastic deformation along the approaching and separating directions with respect to the blade. An adjustment mechanism adjusts a projecting amount of a spring tip portion of the actuating spring from a blade tip portion of the blade.

In a method of manufacturing an electroforming mold, a first photoresist layer is formed on an upper surface of a bottom conductive film of a substrate, and the first photoresist layer is divided into a first soluble portion and a first insoluble portion. A conductive material is thermally deposited on an upper surface of the first photoresist layer within a predetermined temperature range, to thereby form an intermediate conductive film. An intermediate conductive film is patterned. A second photoresist layer is formed on an exposed upper surface of the first photoresist layer after the intermediate conductive film is removed, and on an upper surface of the intermediate conductive film remaining after patterning. The second photoresist layer is divided into a second soluble portion and a second insoluble portion. Next, the first and second photoresist layers are developed, and the first and second soluble portions are removed.
